Sorry for the newbie question, but I was wondering about using foil to cover the bowl. From what I have read on here and from other places, most people seem to prefer foil instead of the bowl screens. I just read somewhere that you shouldn't use household aluminum foil, but buy the foil made especially for hookahs. So, I guess my question is, should I buy the special hookah foil, or would your regular Reynolds or whatever aluminum foil work fine?
